I'm thinking that the name must be coming from your dhcp server or from
the config file for the network adaptor...

what is output of?
grep HOST /etc/sysconfig/network-scripts/ifcfg-eth0

what is providing DHCP to this system?

I'm thinking that the name must be coming from your dhcp server or from

the config file for the network adaptor...



what is output of?

grep HOST /etc/sysconfig/network-scripts/ifcfg-eth0



what is providing DHCP to this system?

Hi Craig,

Still have not determined the cause of the hostname becoming set.* My suspicion now is that it might be DHCP.* I have now reset the hostname by setting up the /etc/hostname file then running "hostname -F /etc/hostname".* I wish I could have determined the cause of this but if what I have done is permanent then I will live with that.

* Thank you again for your help.

Fennix

PS:* Thank you to kalinux as well for your suggestion.* The avahi daemon was running so I have stopped that service (since it definitely is unnecessary) but after rebooting I still did have the bogon hostname for my system.* I have overridden the name using the hostname command and making a hostname file.
